Well, we knew about the Wilco UniPo 6-pack, but UNKL has now released a schedule with all of their exclusives. I'm not sure if I like the whole "release a different exclusive every day" thing, but it assures you that everything doesn't sell out preview night. For someone who isn't going to the show every day, I guess they need to pick and choose.
Here's the schedule:
Thursday July 26th - Wilco UniPo 6-pack (200 sets)
Friday July 27 - Urban Recovery SUG & Ulligus (40 pieces)
Search & Rescue SUG & Ulligus (250 pieces)
Saturday July 28 - Debut of HazMaPo Carbon Series (250 of each)
SDCC '07 Exclusive HazMaPo (40 pieces)
